apache: 管理 - 状态查看

0. 配置状态查看

# 检查配置文件基本语法
/usr/local/apache2/bin/apachectl -t
Syntax OK

1. 模块状态查看

# 查看shared模块和static模块
/usr/local/apache2/bin/apachectl -M
Loaded Modules:
 core_module (static)
 so_module (static)
 http_module (static)
 mpm_worker_module (static)
 ......

# 查看编译在apache中的一些modules，可看出运行模式
/usr/local/apache2/bin/apachectl -l
Compiled in modules:
  core.c
  mod_so.c
  http_core.c
  worker.c

2. APACHE版本及编译参数查询

# 查看httpd版本
/usr/local/apache2/bin/apachectl -v
Server version: Apache/2.4.20 (Unix)
Server built:   May 23 2016 03:26:12

/usr/local/apache2/bin/httpd -v
Server version: Apache/2.4.20 (Unix)
Server built:   May 23 2016 03:26:12
# 效果一样，是因为apachectl本身调用的就是httpd命令


# 查看httpd版本及编译选项
httpd -V
Server version: Apache/2.4.43 (Unix)
Server built:   Apr 23 2020 03:04:31
Server\'s Module Magic Number: 20120211:92

Compiled using: APR 1.6.5, APR-UTIL 1.6.1
Architecture:   64-bit
Server MPM:     event
  threaded:     yes (fixed thread count)
    forked:     yes (variable process count)
Server compiled with....
 -D APR_HAS_SENDFILE
 -D APR_HAS_MMAP
 -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
 -D APR_USE_SYSVSEM_SERIALIZE
 -D APR_USE_PTHREAD_SERIALIZE
 -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
 -D APR_HAS_OTHER_CHILD
 -D AP_HAVE_RELIABLE_PIPED_LOGS
 -D DYNAMIC_MODULE_LIMIT=256
 -D HTTPD_ROOT="/usr/local/apache2"
 -D SUEXEC_BIN="/usr/local/apache2/bin/suexec"
 -D DEFAULT_PIDLOG="logs/httpd.pid"
 -D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
 -D DEFAULT_ERRORLOG="logs/error_log"
 -D AP_TYPES_CONFIG_FILE="conf/mime.types"
 -D SERVER_CONFIG_FILE="conf/httpd.conf"

# 编译参数查看，原理是查看源文件目录中生成的config.nice文件
cat /usr/local/src/httpd-2.4.20/config.nice
#! /bin/sh
#
# Created by configure

"./configure" \
"--prefix=/usr/local/apache2" \
"--with-apr=/usr/local/apr" \
"--with-apr-util=/usr/local/apr/bin/apu-1-config" \
"--enable-rewrite" \
"--enable-so" \
"--enable-headers" \
"--enable-expires" \
"--with-mpm=worker" \
"--enable-modules=most" \
"--enable-deflate" \
"$@"
# 这个只能是在你自己源码编译的安装方式下查看

3，apache服务启动关闭

# 使用apachectl命令(其实是个脚本，调用的httpd命令)
/usr/local/apache2/bin/apachectl start
/usr/local/apache2/bin/apachectl stop
/usr/local/apache2/bin/apachectl restart
/usr/local/apache2/bin/apachectl graceful
